I call him that, because he talks like he's in a Marvel comic book, with sound effects.
He hits head on something, and says, "Bonk!".
He sees somebody sleeping, he says, "Khrrrrrr. Khrrrrrr" (that's his sound for snoring).
He rings the doorbell and says, "Ding Dong!" musically.
He bounces a ball and says, "Boiiinnng! Boiiiinnng! Boiiinnng!".
Walking, talking, entertainment.
